Application led .Tuly 29, 1908. Serial No. 445,867.

To all 'whom it may concern:

Be `it known that we, WILLIAM EAKIN and ROBERT Dnnoo, citizens of the -United States ol" America, residing at Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented certain new and use- `ful Improvements in Flushing-'lanka of which the following is a specilication, relierence being had therein to the accompanying drawing.

This invention relates to flushing tanks designed for llushing closets, hoppers and bowls.

The object of the invention is to provide a simple and inexpensive valve for controlling the outlet of the tank and which can be used either independently of the inlet valve or serve as a float to actuate the inlet valve.

A further object of the invention is to provide means whereby approximately the entire contents oit the tank is removed in flushing.

A further object is to provide a flushing valve of simple construction by meansot which the siphonio action is freely established and cut otl" with certainty.

The invention comprises the construction and arrangement oit parts hereinafter described and claimed.

In the accompanying drawings Figure l is a longitudinal sectional view of the tank showing the parts in the position they assume when the tank is empty; Fig. 2 is a plan view of the same; Fig. 3 is an elevation of a portion of the loat valve; Fig. 4 is a sectional detail view of a slightly modified form of float valve;Fig. 5 is a plan view of a modied form of tank; Fig. 6 is a longitudinal vertical section through the same; Fig.

7 is a transverse vertical section through the same; Fig. 8 is a perspective view of the valve actuating means; and Fig. 9 is a detail view of the means for adjusting the float lever.

In the drawings l. designates the tank which may be of any suitable shape and constructed of any suitable material, being shown as rectangular in 'forni and constructlet `pipe which extends` upwardly toward the top olf' the tank to such height that its upper end is above the normal level of water contained in the tank. Preferably the top of this pipe is flared as shown at l.

At 5 is shown the inlet pipe provided with an inlet valve 6 which is controlled by a float lever 7. The inlet pipe and valve may be of any suitable form.

rlhe outlet valve is in the form of a hood, or inverted cup, located over and around the outlet pipe. As shown in Figs. 1-5 the valve comprises a box-like structure 8, of square or rectangular form in plan view; provided with exterior vertical walls 9 and inclined or downwardly flaring interior walls l0, the lower edges oli' said walls being recessed or cut away as shown at ll on two opposite sides of the box-like structure. This boxlike structure supports the hood proper l2 located over the upper end of the outlet pipe, and heilig practically a continuation of lthe interior walls 10 olf' the boxe like structure, the space in said hood commu nicating freely with the space in said box like structure. ln the preferred forni the valve is so constructed as to be buoyant so that functionally it serves both as an outlet .Valve and as a float for actuating the inletvalve. The buoyancy may be secured in any suitable way, but preferably by inclosing the space between the exterior walls 9 and interior walls 'l0 so forming a hollow float which takes the place of the ball float ordinarily employed.

ylhe valve described 1s guided vertically by walls or partitions 13 shown as extending transversely of the tank and contacting with the vertical walls 9 of the l'loat valve. The walls or partitions 13l are provided at their lower edges with restricted openings let forming communication between the space inside the iloat valve and the main body of the tank. The valve is actuated by depress ing the same and a convenient means for this comprises a shaft 16 journaled in the side walls of the tank and provided with a square end 17 :tor receiving an arm 18 or other operating means. The shaft 16 is provided with arms 19 whose outer ends are connected to, or contact with, oppositely disposed trunnio'ns 20 carried by the hood 12. The float valve may be operatively connected to the float lever 7 by various means, the drawings la in the partitions 13. When the tank i is full the iioat valve will be in elevated position (not shown), thus holding the inlet valve 6 closed. In this position the water level is somewhat below the top of the outlet pipe. In order to flush the tank, shaft 16 is rocked to force the float valve downwardly between the partitions 13. Since the openings let in said partitions are of comparatively restricted area the water within the float valve which is displaced by the downward movement of the valve cannot escape through said openings sufficiently rapidly and therefore the water level within the float valve is temporarily raised above the top of the outlet pipe. The latter becomes sealed by the water entering the same, and as said water flows downwardly through said pipe it sets up siphonic action which draws the water out of the tank, the water of the main body of the tank flowing through the openings 14 in the partitions 13 and thence upwardly in the float valve and down through the pipe 3. Since the interior of the float valve is entirely unobstructed the siphonic action is rapidly formed when the valve is depressed. The siphonic action continues until the level of the water drops below the upper edges of openings 11 and 1/1 after which air is permitted to enter and breaks the siphonic action. Consequently the tank will be drained of its entire contents with the exception of the water contained in the depressed portion 2.

n Fig. et is shown a modification wherein the float valve instead of being provided with the cut away portions 11 is provided with feet or lugs 28 which serve to hold the body of said valve above the bottom of the tank and give the same effect as though the valve were provided with cut away portions.

vFigs. 5, 6 and 7 show a modification in which the exterior walls 9 of the float valve are omitted. In this modification the valve is not buoyant and an independent ball iioat 25 is provided on the lever 7 of the inlet valve. In this modification the hood valve normally remains in its lowermost position and in order to actuate the same it is necesthe same to overflow the outlet pipe and set up siphonic action. 11i-'order to deaden the noise when this valve strikes the bottom of the tank it is provided with cushions 24.

rl`he hood valves described are shown as formed of sheet metal, and while this is preferred, we wish it understood that the invention is not limited thereto, as said valves may be formed of any suitable durable material. For convenience and cheapness of construction the square or rectangular form of valve shown is preferred, as it can be constructed with a minimum waste of material and also enables the use of simple straight partitions extending across the tank from side to side. Certain features of our invention however, are not limited in this par ticular but are equally as well adapted to float valves of circular or other form and with confining and guiding walls of similar form.
